Environmentally friendly and rapid mounting construction method for rapidly mounting shield tunnel electromechanical equipment pipelines

Abstract

The invention discloses an environmentally friendly and rapid mounting construction method for rapidly mounting shield tunnel electromechanical equipment pipelines. A segment bolt penetrates through prefabricated hole positions in shield segments to connect and fix the adjacent shield segments; by using parts, exposed out of the shield segments, of the segment bolt, assembled lugs are mounted on the shield segments; and an arc toothed external slide groove penetrates through the cavity of the assembled lug to be formed in the internal side of an arc of the shield segment in the circumferentialdirection of the shield segment. As all parts are mounted in an assembled manner without drilling holes in tunnel segments, the construction speed is high, the integrity of a tunnel structure is notdestroyed, the environmentally friendly and rapid mounting construction method replaces a traditional perforation and steel implantation process, the service life of the tunnel structure is prolonged,the mounting mode is comparatively flexible and convenient, the tunnel structure can be arranged according to actual needs, and the construction and maintenance cost can be reduced; and according tothe environmentally friendly and rapid mounting construction method for rapidly mounting the shield tunnel electromechanical equipment pipelines, waste water, waste gas and waste slag are not generated in the construction process, noise pollution and dust pollution are not generated in the construction process, and the health and safeties of construction personnel are protected.

Description

technical field [0001] The invention relates to the technical field of quick installation of pipelines, in particular to an environmentally friendly quick installation method for quickly installing pipelines of electromechanical equipment in shield tunnels. Background technique [0002] With the rapid development of the national economy and the acceleration of the new urbanization process, in recent years, my country's urban rail construction has developed rapidly. The road tunnels and subway tunnels in many cities are constructed using shield technology. The use of shield technology for tunnel construction has a high degree of automation, saves manpower, fast construction speed, one-time hole formation, is not affected by climate, can control ground subsidence during excavation, reduces the impact on ground buildings and excavates underwater. It is more economical and reasonable to use shield technology for construction of urban highway tunnels and subway tunnels without a...

AI Technical Summary

Problems solved by technology

[0003] Using traditional technology to drill a large number of holes and install anchor bolts on the concrete structure in the shield tunnel, not only the work efficiency is low, the dust is large, but there are also potential safety hazards such as possible damage to the segment structure. Severe damage will affect the service life of the project, and the anchor bolts The process also has disadvantages such as slow construction speed, poor construction environment, and high post-operation and maintenance costs.
